Abstract (en)
[origin: EP4199186A1] The present application provides a charging and heating apparatus and a method and apparatus for controlling a charging and heating apparatus. The charging and heating apparatus includes: at least one power unit each of which being configured to be connected to a battery to be charged/discharged and perform voltage conversion on a received voltage and current and output a converted voltage to the battery; a unidirectional/bidirectional conversion unit connected to each power unit and configured to output a first bidirectional alternating current or a preset current to the at least one power unit; and a control unit connected to the unidirectional/bidirectional conversion unit and configured to: when the battery is in a heating mode, control the unidirectional/bidirectional conversion unit to output the first bidirectional alternating current to the corresponding power unit, such that the battery self-heats under excitation of the first bidirectional alternating current; and when the battery is in a charge/discharge mode, control the unidirectional/bidirectional conversion unit to output the preset current to the power unit, such that the battery is charged/discharged.
